Just a coin set.
These are not proof coins but UNC.
Value is not much (here in Belgium)
About €15 maximum

The are just unc but not the proof one. I was trying to find this set on eBay or at the other websites but I didn't find it anywhere. That's why I ask here to forum. The 2 big are silver but I start looking for information about this serie because I don't like the quality of the silver coins.

the 250fr are with the small 'B'
The looks of these coins seems ok.

​Bullion value of the 2 coins of 250 francs is more than 15 euros...
I think 25euros would be a more appropriate price.

Thank you also for the information.
